Win32lib V0.54 Changes
I'm about to release version 0.54 of Win32Lib to the sourceforge site.
There will be three ZIP files,
1) The library, include files and examples. These source files are without
comments etc.
2) The documentation in HTML form
3) The library files with full comments and formatting.
Here is a summary of the changes...
-------------------------------------
Fixed. Can now use setHint() an a top-level window.
Fixed. No longer triggers an onScroll event if the scroll position hasn't
actually changed.
Fixed. Now handles setting focus after a control has been destroyed.
Fixed. The freeing of string memory has been made reenterant.
Fixed. getMultIndices() and getMultItems() now cope with no items selected.
Fixed. No longer crashes when a TVN_DELETEITEM event occurs for treeview
controls.
Fixed. The use of Modal windows no longer crashes the Application.
Enhanced. warnErr() now allows the user can now opt to ignore repeated
warnings.
Enhanced window scrollbars. Standard scroll bars on windows windows now
trigger onScroll events
Enhanced. create(), createEx(), setClientSize(), setCtlSize(), setRect(),
and setPenPosition()
In addition to the current method, you can now supply dimensions
relative to the control's parent in terms of percentages, plus
optional pixel offset. You can even align things to the edges of
the parent. Optionally you can specify minimum and maximum
sizes.
Enhanced.
Extra validation is being done to ensure that Window Handles are
being used with the correct control ID.
Enhanced
The event handlers onXXX can now be set for the Screen ID. This
will capture all events of the given type for all controls in
the application. For example onKeyDown[Screen] will be fired
for all KeyDown events on all controls.
Enhanced
getTextExtent() now takes either a single text string or
multiple strings. It returns the maximum, minimum and total
pixels for width and height. This change will not effect
existing code.
Added getCharExtent()
This returns the average width and height for a text character
in a given control.
Added getVScrollPos(), getHScrollPos(), setVScrollPos(), setHScrollPos()
These get and set the Vertical and Horizontal positions of
scrollbars that are attached to windows via the WS_HSCROLL and
WS_VSCROLL
Added classDefaults()
This allows you to set the default styles for each control.
Added setClientRect()
This resizes your window so that the client area is as specified.
Added doEvents()
This allows Windows to check for message events during event
handling.
Added acquire_mem(), release_mem(), new_memset(), and manage_mem()
These are the new memory management routines that are used in
win32lib. The use of free(), allocate() and allocate_string()
is discouraged inside win32lib.ew. Please use the new routines
instead.
Added getPosition()
This returns a sequence containing the pixel position of the
top lefthand corner of the control
Added copyFile(), deleteFile(), moveFile(), createDirectory(),
getTmpPath(), getTempFile()
These are wrappers for the Windows file/directory commands.
Added openDialog()
This simulates a dialog-type window. It opens the specified
window and directs all events to that window until its closed.
Added showChars()
This function sets an internal flag that causes wPrint() to
show displayable characters in readable form. The initial setting
is to show such characters like Euphoria's print() function.
Added eucompress.exw
This is a Windows program that compresses any euphoria source
code by removing unrequired spaces, empty lines and comments.
Changed
setPosition() has been renamed to setPenPosition()
Changed
moveWindow() has been renamed to setRect()
Changed
getExtent() has been renamed getCtlSize()
Changed
getSize() has been renamed to getRect()
Changed
setSize() has been renamed to setCtlSize()
Changed
The routines renamed above are actually still defined in
a compatability file "compat01.ew" which will not be distributed
when version 1.00 is released. This file is automatically
included in the library for now, but from v1.00 onwards will be
distributed but not included inside win32lib.ew
Changed
The distribution now comes with a number of toolkit files.
tk_mem.e (memory management)
tk_maths.e (Mathematical functions)
tk_misc.e (Miscellaneous)
These can be used with any Eu project.
These files are "included" by win32lib.ew
An additional file, tk_fileio.e, is also distributed but it is
not used by win32lib.
Changed.
onClick events now fired for all non-static controls that don't
capture mouse events. For example, the StatusBar.
Changed
Now uses the DoubleClick time interval for the maximum mouse
click time tolerence.
Changed
For those routines that deal with positioning controls etc, the
X and Y (left and top) coordinates are relative to the parent's
client area, not the parent's borders.
This may break some code that currently manually adjusts these
values to account for Toolbar and StatusBar controls. These sort
of adjustments are now done automatically.
Removed.
The routines free_strings(), allot_string(), and
allocate_struct() have been removed.
